| - | LSPHP(LSAPI + PHP) command line mode is for PHP binary running on a remote server that does not necessarily have web server running to process PHP scripts reside on local web server (separate). This setup is suitable for service scalability as PHP processing is offloaded to a remote server. | + | Usually, LSPHP(LSAPI + PHP) is managed by LiteSpeed Web Server. In a clustered environment, though, with a single LiteSpeed Web Server or LiteSpeed Web ADC load balancing LSPHP processes running on multiple backend servers, it may be necessary to start LSPHP processes manually. LSPHP is an executable and can be started manually and bound to IPv4, IPv6, or Unix domain socket addresses with the command line option ''-b socket_address'' |

| - | Environment variables (please check [[litespeed_wiki:php:lsapi-environment-variables#environment_variables_configurable_at_lsphp_external_apps|here]] for a list of supported variables) can be added before the LSPHP executable. The `PHP_LSAPI_CHILDREN=nn` is required when run lsphp as a service to handle concurrent requests, `nn` should be, minimum, the concurrent level required by the frontend. It is running PHP in process group mode. Note the following are only example figures, and you should adjust it to meet your need. | + | Environment variables (please check [[litespeed_wiki:php:lsapi-environment-variables#environment_variables_configurable_at_lsphp_external_apps|here]] for a list of supported variables) can be added before the LSPHP executable.
